<br />1 Basin I has shown no evidence of silt or sediment accumulation. Ground cover within Basin I <br />consists of native grasses and some transplanted trees. <br />1 <br /> Basin II (0.52 acres) is situated offsite az the northwest wmer of the proposed pit Runoff <br />' discharges easterly as sheet flow into proposed pit area with slopes of 25%. Basin II is <br /> heavily vegetazed with Gambrel Oak, Mountain Mahogany, and native short grasses. If <br /> preserved, this ground wver will serve to enhance the visual aspect of the pit area, diffuse <br />' surface runoff and inhibit downstream sedimentation <br /> Basin III (2.86 acres) is simated in the northwest comer of the proposed pit and is contiguous <br />' with Basin II. Runoff occurs as sheet flow discharging to the northeast through a natural draw, <br /> a[ which point channelized flows develop. The natural draw exits the proposed pit on the <br />' north side and empties into Beaver Creek. Ground cover is comparable to Basin II. <br /> Basin IV (0.70 acres) is located within the northeast portion of the proposed pit and feaztttes a <br /> natural draw opening m the northeast Runoff from Basin IV discharges within this draw to <br />' Beaver Creek. <br />' Basin V (4.76 acres) is located within the east central portion of the proposed pit Runoff <br />occurs as shee[ flow on 25% slopes, discharging easterly through a natural draw and <br /> eventually to Beaver Creek. <br />' Basin VI (6.13 acres) is composed of natural ridges and a major drew with slopes varying <br /> from 25% in the east half, lower end to 3% in the upper or west half. Grotmd cover within <br /> this area is mostly short grass gambrel oak and mountain mahogany. An existing Ranch Road <br />' follows the course of the major draw and provides access to the reclaimed pit area above. Due <br /> to the conswction of the road and its location, erosion has occurred along the lower roadway <br /> edges in the southeast portion of the proposed pit. All runoff from Basin VI follows the <br />' course of the roadway, exiting the pit area and discharging into the lower sedimentation pond <br /> from the northwest. The pond is capable of retaining approximately 4 acre feet of nmoff <br /> before overflowing to the southeast. There is evidence of sedimentation and silt collection <br />' within the pond area most of which occurs from normal storm runoff. Below the <br /> sedimentation pond, existing slopes will discharge easterly to Beaver Creek above its <br /> confluence with Hay Creek. These slopes exhibit good vegetation and ground cover. <br />' <br /> Basin VII (0.13 acres) is located in the extreme southwest portion of the proposed pit along a <br /> saddle discharging southeasterly m Hay Creek. <br />' Basin VIII (7.01 acres) is located on the southeast pit exterior, encompassing the existing <br /> access road and the sedimentation pond. Drainage through Basin VIII originates from Basins <br /> VI and I above and occurs as shallow concentrated flows within the roadway, being eventually <br />' detained in the lower pond area. Ground cover vanes due to the presence of the roadway. <br /> Presently, there is visible erosion only in Basins VI and VIII due m the channeling effects of <br />the road. Basin VIII also contains the sedimentation pond area. Erosion damage is non- <br /> existent in Basins II, III, N, V or VII due to the dense brash and ground cover. The <br />' P-11 <br />1 <br />
